Specification of Letters Patent.

Patented Oct. 27, 1914.

Application led May 25, 1914. Serial No. 840,877.

To all whom t may concern: s

Be it known that I, CHARLES E. BERRY, a citizen of the United States,residing at Someiwille, in the county of Middlesex and State ofMassachusetts, have invented a new and useful I-Iydiant-lrench, of whichthe following is a specification.

This invention relates to a hydrant wrench, one of its objects being toprovide a simple andcompact device of this character for use inconnection with screw heads of different sizes whereby the wrench can beused in connection with different makes of hydrants.

A. further object is to vprovide a simple form of spanner in connectionwith the wrench by means of which hose-can be attached readily to ahydrant, thus rendering the tool especially desirable for use by firedepartments.

`With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

1n the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings r-Figure 1 is a side elevation of a wrench embodyingthe present improvements. Fig. 2 is a front elevation thereof. Fig. 3 isan end elevation. Fig. 4 is a section on line A--B Fig. 2.

Referring to the figures by characters of reference, 1 designates anelongated handle or shank merging, at one end, into a ring 2 from whichextends outwardly diverging arms 3 connected by an arcuate web 4, thesearms 3 being formed with longitudinal slots 5 while the web l is alsoslotted longitudinally, as shown at 6. The arms 3 and the web etconstitute a spanner whereby hose can beconnected to a hydrant in theusual manner, as will be obvious. The spanner and the shank 1 aredisposed at diametrically opposed points on the ring 2. The innersurface of the ring is formed with diametrically opposed flattened faces7 equidistant from the handle 1 and extending through each flattenedface is a pivot screw 8, the inner end of which constitutes the bearingtrunnion as shown at 9.

'A ball 10 is arranged loosely within the ring 2 and has opposedflattened faces 11 each of which is formed with a socket 12 designed toreceive the bearing portion 9 of one of the screws 8. The ball isbalanced upon these trunnions and is adapted to rotate readily withinthe ring 2. Formed within the ball are radially disposed pentagonalsockets 13 of different sizes. Preferably four of these sockets areemployed, the ball being formed with flattened faces 14 where thesesockets are located. A reinforcing barl 15 is formed integral with theball and extends diametrically therethrough in alinement with the pivotor bearing 9.

Extending from one face of the shank or handle 1 is a boss 16 having apentagonal socket 17 in its outer end and, formed in the inner end ofthis pentagonal socket is a smaller rectangular socket 18, as shown in Fig. 2.

In using the wrench, the ball 10 is rotated until a socket 13, whichwill fit the screw head to be rotated, is brought into position toengage said screw head. As the screw heads of various makes of hydrantsvary in size, it will be seen that by utilizing a ball 10 having socketsof different sizes, the same can be fitted readily to screw heads ofdifferent sizes. Moreover, as all of the sockets are located in a ballmounted for rotation, it will be seen that the handle will always occupythe same relation to any one of the sockets 13 into which the screw headof the hydrant may extend.

Many hydrants are provided with small outlets controlled by a valve, thestem or actuating screw of which has a compara# tively small head. Theseheads are somewhat rectangular and some times pentagonal.y Forthekpurpose of engagingand rotating these small heads, the boss 16 hasbeen provided, socket 17 being used for receiving a pentagonal head,while socket 18 is provided for receiving a rectangular head.

The bar 15 not only serves to reinforce the ball 10 but also constitutesa stop for limiting the movement of the engaged head of a screw into theball.

What is claimed is A wrench including a ring, a handle extendingtherefrom, said ring having its wall thickened at diametrically opposedpoints,

bearing elements screwed into said thick- In testimony that I claim theforegoing ened portion and projecting into the ring, as my own, I havehereto ztixed my sig- 10 and. a ball mounted for rotation on the4vns1-ture in the presence of two Witnesses.
